- Albatros D.IX
Albatros D.IX was a German prototype single-seat fighter built in early 1918. It differed from previous marks by using a simplified
fuselagewith a flat bottom and slab sides. The wings and tail were similar to those of the Albatros D.VII. Power was provided by a 180 hp Mercedes D.IIIa engine. The D.IX was armed with twin synchronised LMG 08/157.92 mm machine guns.
The prototype exhibited disappointing performance and the project was discontinued.
